 - **必须实际运行并截图，不能只看代码**
 - 2026-03-13：补齐 `src/core/tests.rs` 的关键路径覆盖，重点覆盖动态插件 FFI 返回 null 的降级、无效 manifest 跳过、禁用插件消息跳过、无稳定版本回退失败、以及 `Message` 全变体 JSON round-trip
 - 2026-03-14：新增 `tests/m1_2_service_manager.rs`，补齐 M1.2 ServiceManager 集成测试基建，覆盖依赖启动顺序、Shutdown 停机、ConfigReloaded/PlayerStatus/WifiResult/StateChanged/PluginReady 广播，以及禁用插件路由跳过
+- 2026-07-02：M1.2 目标机验收（Linux ARM64）。经验：① 跑全量测试前先 `df -h`——ARM 设备 28G 盘 98% 满导致 ld 链接失败（No space left on device），清 target/debug/incremental + 过期 deps 即可，不必 cargo clean 全量重编；② cargo test 默认 fail-fast，验收要加 `--no-fail-fast` 才能拿到全部 target 的统计；③ "从未实跑过的测试"是最大风险源——test_empty_playlist_does_not_panic 的前提（空 playlist 可加载）与 config.rs 自 init 起的校验矛盾，代码评审没发现，一跑就露馅；④ 同步版本用 git bundle + fetch + merge --ff-only 最安全，先确认祖先关系和设备脏文件不在 diff 内
+- 2026-07-03：M1.2 第二轮（返工后）验收全绿 147/147 零 warning。经验：scp 未提交文件到设备时必须两端 sha256 对账，并在交付中显式标注设备与 git HEAD 的不一致状态，提醒 commit 后重新同步
